Answer:


\huge\boxed{\sf b = 8.7 \ cm}

Explanation:

Given equation:


\displaystyle tan (30 \textdegree) = (5)/(b)

We have to find b.

tan 30° = 0.6


\displaystyle 0.6 = (5)/(b) \\\\Multiply \ b \ to \ both \ sides \\\\0.6 * b = 5 \\\\Divide \ 0.6 \ to \ both \ sides\\\\b = (5)/(0.6) \\\\b = 8.7 \ cm \\\\\rule[225]{225}{2}
